Comparison of the Results of Blood Test in Dogs with Tumor and Healthy Dogs

Abstract

The results of complete blood count and blood chemical analysis were compared between 164 tumor-bearing dogs and 26 clinically healthy dogs as a control. The dogs with a tumor were sorted into five groups；group 1: dogs with benign epithelial tumors; group 2: dogs with malignant epithelial tumors such as malignant mammary gland tumor and malignant melanoma; group 3: dogs with benign mesenchymal tumors; group 4: dogs with malignant mesenchymal tumors such as hemangiosarcoma; and group 5 :dogs with round cell tumors such as lymphoma and mast cell tumor. Further, the dogs with six major tumors were grouped separately, and their blood data were calculated individually. Namely, group A consisted of the dogs with benign mammary gland tumors, group B, the dogs with malignant mammary gland tumors, group C, those with malignant melanomas, group D, those with hemangiosarcomas, group E, those with lymphomas, and group F, those with mast cell tumors. The red cell count was significantly decreased in groups 5, D, and E. Hb and PCV were significantly decreased in groups 2, 4, 5, C, D and E. The white blood cell count and segmented neutrophil count were significantly increased in groups 2, 4, 5, B, D and E. The platelet count was significantly increased in group 2, and the platelet count was significantly decreased in group D. Glb, ALP, Ca and CRP were significantly increased in groups 2, 4, 5, B, and F. LDH was significantly increased in group E. This study suggested that routine blood tests might provide useful information for diagnosis of tumors.
